Question

Quizplus · Accepted Answer

The concept described in the question is inheritance, which is the mechanism through which properties and behavior of a higher-level class, called a superclass or parent class, are passed down to its lower-level subclasses or child classes. This allows for the economical representation of information in a hierarchical model, where attributes and methods that are common to all members of a certain class can be defined at a higher level and inherited by its descendants. Subsumption, class-inclusion statements, and superordinate feature acquisition are related concepts but do not fully capture the idea of inheritance in object-oriented programming.
